OAT=HULL|NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 346,933, dated August10, 1886.

Application filed November 9, 1885. Serial No. 182,172. (No model.)

T0 @ZZ whom it may concern.:

Be it known that we, WILLIAM MATTHIAs and CHARLES E. RUDOLPH, citizensof the United States, residihg at Colfax, in the county of Richland andTerritory of Dakota, have invented certain new and useful Improvementsin Oat-Hulling Machines, ofwhich the following is a specification.

Our invention relates to machines for removing the hulls vfrom oats; andthe object of the invention is the production of mechanism which willeffcctually remove from the oatkernels both the outer hulls and theinner coverings or skins, together with thefuzz. This object isaccomplished by the mechanism illus'- trated in the accompanyingdrawings, in which f Figure l is an elevation of the front of themachine; Fig. 2, an elevation of the rear of 'the machine; Fig. 3, aside elevation; Fig. 4, a sectional view of a portion of one of thecylinders, showing the beaters within. Fig. 5 is 'a detached view of oneof the beaters, and Fig. 6 is a transverse sectional view of the same.

A represents the posts, and A the crosspieces, of thc frame-work of themachine.

a is a vertical partition extending lengthwise through the frame.

bis a trough or other suitable receptacle for the particles which passthrough the sides of the cylinders and fall below, and the trough isdivided by the partition a into two compartments.

c c are worm-conveyors for carrying away the matter which falls into thetrough.

e c e2 and e e* e5 are two sets of hulling cylinders or jackets, placedlengthwise in the frame, and arranged in vertical series on oppositesides of the partition a. These cylinders are of sheet metal, inclosedby wooden heads o, which are lined with sheet metal, and the heads aresecured to the ends of the framework. The jackets are perforated withindented slots t, in size about one-half by one` thirty-second of aninch, and the perforations run longitudinally with the jackets and areThe inner surface of the jackets are thus made rough. At the side ofeach jacket, toward the outside of the machine, are a number ofopenings, f, of suitable size to admit a hand, and over these openingsis a slide, d, having openingsf, the saine distance apart as theopenings f. The slide has a handle, d', at one end of the machine, andworks in grooves formed by strips r, of metal, riveted to the jackets,and may be adjusted to open or close the holes j'. By opening the' holesaccess can be had to the interior ot' the jacket for adjusting thebeaters or for removing foreign substances. Through the jackets eX- tendshafts g, whose bearings are in boxes h on the cross-pieces A. Theportions of these shafts within the jackets are covered with wood, t',for securing the beaters. The beaters 7c are set in rows parallel withthe shafts, and the teeth of each row are placed slightly-about ahalf-inch-in advance of those of the preeeding'row, for the purpose ofconducting the grain toward one end of the jacket. The beaters in thefirst series, e c e, of cylinders are set to rotate within aboutone-fourth inch of the inner surfaces of the cylinders, and those of thesecond series, e3 e* e5, are set to rotate within about one-half inch ofthe cylinders.

The beaters consist of square Shanks threaded at one side forinsertingand adj listing them inthe wood z' of the shafts, and the other ends areforked, and the arms of the forks 7a are made triangular incross-section. The angular edges of the forks are placed in thedirection of the shafts7 rotations.

To cause the grain to vbe conducted more speedily through the jackets,the beaters may be slightly turned by means of the threaded ends in thewood, so as to present more of the fiat surfaces of the forks, and thuscarry the grain along faster, and in this manner the length of time thegrain is subjected to the beater action is reduced.

The shafts g may be driven by a belt (shown by dotted lines m) ruimingover pulleys n and tightening-pulley u', in the manner shown. l

The conveyers c c' are operated by a belt, m, (shown by dotted lines,)running over pulleys a? on the conveyer-shafts and o1. on a shaft, g,run by the pulley u.

In operating the machine the oats are fed into the rear head ofthejacket e through a spout, s. The feed is made regular by means of afeeding-shoe, o, suspended above the IOC spout s, and shaken by apitman-rod, p, operated by an eccentric, q, on the beater-shaft of thejacket e. The oats, being conducted through the jacket e by the actionof the beaters, pass out of the head v through an opening into the spouts,which conducts them into an opening in the head of the jacket e. Afterpassing through the jacket e', they are directed into the head of thejacket c'l by a spout, s2. Vhen they have been passed through the jackete2, they fall into a spout, s, and are elevated to the top of themachine by an ordinary elevator,(not shown in the drawings,) which maybe run by the shaft g. The beaters of the first three jackets remove thedirt and most of the hulls from the kernels, and the portions removedare forced through the slots t, and fall into the conveyer-box, to becarried away by the conveyer c. The oats, after being elevated to thetop of the machine, are spouted through aspout, s, into the rear head ofthe jacket e, for a less severe treatment than that given by the firstseries of beaters. Passing through the jacket e, the oats enter throughthe spouts s5 into the front end of the jacket e", thence from its rearend through the spout s into thejacket c5, and from the front end ofthis jacket the cleaned kernels are discharged from the machine throughthe spout 8'. The last set of beaters remove the skins and fuzz from thekernels, and the particles removed pass out of the slots t and fall intothe conveyer-box beneath, to be carried away by conveyer c.

Having fully described our invention, what we claim, and desire tosecure by Letters Pat ent, is` v ystraight Shanks and forkedangularextremities, substantially as set forth.

2. In an oat-hulling machine, the combination, with a frame and ahorizontal cylinder 45 perforated with indented slots, of a shaftextending through said cylinder and beaters mounted on said shaft, saidbeaters having one end threaded and screwed into said shaft and theother provided with forks of angular form in crosssection, and arrangedto conduct the grain from one end of the cylinder to the other,substantially as set forth.

3. The combination, in a machine for hul1- ing grain, of a frame, asuccession of horizontal cylinders perforated with indented slots,shafts through said cylinders, beaters having straight shanks and forkedangular extremities, mounted on said shafts to conduct the grain fromone end of the cylinders to the other, and spots for conducting thegrain from one cylinder to another, substantial] y as set forth.

4. In ahulling-machine, the combination of a horizontal cylinder havingindented perforations, openings fin its side, the slide d, the shaft g,having casing t', and the beaters k, provided with angnlar forks k',substantially as Set forth.
